background: the aim of study was to measure particle matter concentration (pm 1, pm 2.5 and pm 10 ) during normal, semi-dust and dust-event days. the impacts of some meteorological factors on particle matter concentrations were also investigated. methods: samples were collected by grimm aerosol technik (gmbh model 1/108 germany) from november 2011 to may 2012. temperature, humidity, wind speed ...

this study was focused on measuring air pollutants emission from factories producing the asphalt related products in delijan industrial estate, which is the main center of asphalt related products in iran. emissions of four factories were analyzed for air pollutants using a stack analyzer, testo 360, testo co., and germany. the average concentration of all measured stacks for pm, thc, co, nox, ...

The existence of dark matter is supported by a range of relatively simple observations and has been known for about half a century. Supersummetry theories offer a framework for introducing candidates that have the observed characteristics of dark matter. The Lightest Supersymmetric Particle (LSP), such as the neutralino, is the best of such candidates. Inferences about the neutralino’s importan...

the current regulated particle metric in vehicle emissions is the total mass, while during last decade interest in number size distribution has increased. various international studies on epidemiology and toxicology have reported the adverse effect of the particle matter on public health. the unece group of experts on pollution and energy (grpe) under particle measurement program (pmp) are unde...

In this study, the effect of some processing parameters on bulk density, particle density, particle size and some of powder reconstruction properties such as dispersibility, Wettability and water solubility index of spray dried barberry (Berberis vulgaris) juice powders were investigated. A Pilot Spray Dryer (Two- Flow nozzle, counter- current, one cyclone) was employed for the spray d...

There is plenty of evidence that most matter in the universe is dark (non–luminous). Particle physics offers several possible explanations. In this talk I focus on cold dark matter; the most promising candidates are then axions and the lightest supersymmetric particle. I briefly summarize estimates for the present relic density of these particles, and describe efforts to detect them. To appear ...

The next decade will bring massive new data sets from experiments of the direct detection of weakly interacting massive particle dark matter. Mapping the data sets to the particle-physics properties of dark matter is complicated not only by the considerable uncertainties in the dark-matter model, but by its poorly constrained local distribution function (the ‘‘astrophysics’’ of dark matter). I ...
